IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame.

center, and consists in forming this hub1 in such a manner that thelabor of fitting in these is considerably reduced as compared to theusual modes of mortising, casting in, Suc.

This class of turbines, as is generally known, consists of two parts,one called the wheel proper, and containing the buckets, Vand the othercalled the stationary wheel or guide-plate, containing the guides'. Bothof these have similar hubs and rny invention refers alike to each.

Figure l is a perspective view of the wheel complete.

A being the` guideplate, and K B, the wheel.

H and H,'are the hubs.

Figure 2 shows this huh, also in perspective,

and somewhat enlarged, and it is to the peculiarities of' this that myinvention refers.

These hubs are made of cast-metal, and the wood pattern from whichtheyare cast is made in two pieces, fm and fn,by sawing it apart on thelines c c c c c and a a a a a, (being continued around it in the sameorden) thus forming two notchedor serrated pieces, the object being thatthe lines c c c c, 85o., shall forni inortises or recesses for thetenons ot' the buckets or guides.

rlhe metal on these lines is about one inch thick and the the tenons arecut about this length.

The shoulders fit snugly onto the hub at either side `and slight notchesor grooves are out as contiuuations of the i'nortise in the rightdirection for the proper shape of' the bucket or guide, quite up to theface ou .either side. Common bolts with countersunk heads, as in fig. 1,and with nuts on the other end, as shown in fig. 2, (the hub here beingupside dow11,) are used to bolt and bind the whole together, griping thetenons as in a vise.

After the guide/s or buckets are turned or filed off true on the face orcuter edges, common wrought-iron bands are shrunk on, bindingthe wholetogether.

It will be noticed that the lines c c c c, &c., may be cut curved orstraight, as needed, for the buckets or the guides.

The rims of the wheel and guide-plate may be turned off true to make awater-joint in any of the usual ways.
